title: Percutaneous vertebroplasty in symptomatic hemangioma versus osteoporotic compression fracture.
abstract: BACKGROUND
  Percutaneous vertebroplasty (PVP) is more commonly used for osteoporotic compression fractures (OCFs) and osteolytic vertebral body tumors. This study aimed to study the differences between OCFs and vertebral hemangiomas (VHs) treated with PVP.
  
  
  METHODS
  Between September 2007 and January 2010, we prospectively treated 28 consecutive patients of OCFs (43 recently symptomatic OCFs) and 24 cases of VHs (26 VHs). We used visual analogue scale (VAS) pain and Oswestry Disability Index (ODI) to evaluate the patients. The followup period in group 1 and 2 were 25.1 months (range 12 - 31 months) and 21.3 months (range 14 - 28 months), respectively. Comparison of means was carried out with the Chi Square Tests, t-test, and N Par-Test for multiple comparisons, whenever appropriate. The level of statistical significance was set at P < 0.05.
  
  
  RESULTS
  Following PVP the VAS score decreased to 4.57 and 4.17 in group 1 and 2, respectively. The ODI scores were 32.5% and 30%, respectively. This decrease in ODI scores lasted throughout the followup period.
  
  
  CONCLUSIONS
  Although the preoperative scores were significantly different between group 1 and 2, there was no significant difference between two groups following the PVP.
